#1 Updated by qhwt+dfly over 7 years ago

This may or may not be fixed by turning on the interpreter slack support;
modify /sys/dev/acpica5/acpi.c as follows and rebuild the acpi.ko and
reboot:

/*
* Set the globals from our tunables. This is needed because ACPI-CA
* uses UINT8 for some values and we have no tunable_byte.
*/
AcpiGbl_AllMethodsSerialized = (UINT8)acpi_serialize_methods;
AcpiGbl_EnableInterpreterSlack = TRUE; <== ADD THIS

I didn't commit this simple change apart because I saw the following note
in changes.txt in newer version of ACPI-CA source code:

12 May 2006. Summary of changes for version 20060512:

1) ACPI CA Core Subsystem:
:
Fixed a possible memory leak associated with the support for the
so-called "implicit return" ACPI extension. Reported by FreeBSD,
BZ #6514. (Fiodor Suietov)

Cheers.

Hi there Yonetani,

I saw you were preparing an ACPI update. How far away are you from
comitting it?
